The answer is natural selection.
In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. Darwin's theory suggested that there are variations
among individuals in a population and that these variations will help individuals to survive.
Answer:
C
Explanation:
It moves across the cell membrane via simple diffusion, a process that requires no energy input and is driven by the difference in concentration levels on each side of the cell membrane.
A controlled experiment is when the experimenter can change one variable in the experiment and completely change the results.
Redi experiment involved a closed jar with rotting meat on the inside. He waited for a few days and found no new forms of life in the jar.
He then did the same experiment, but this time he took the lid off the jar. After those few days he found there were maggots in the rotting meat from flies.
This is a great example of a controlled experiment, because he only had to change one variable to completely change the results. In this case that variable was just removing the lid from the jar.
Redi was trying to prove spontaneous generation with his experiment. Although, it failed.
Spontaneous generation: When life forms from non-livings.
Redi disproved spontaneous generation, but proved biogenesis.
Biogenesis: When life comes from other living beings.
He proved biogenesis because the flies had reproduced when the jar was opened.
These jobs are geneticists and criminologists! Geneticists study genes and how they're inherited, seeing where the DNA came from. Criminologists will supply the samples to the geneticists, as they take them from the crime scene.
